Application filed February 25, 1913. Serial No. 750,564.

To all whom itmay concern:

-Be it known that I, AARoN WOOD HAM- AKER, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and useful Improvement in Fly-Killing Devices,

of which the following is a full, clear, and exact specification.

This invention relates to a class of devices adapted to be used for destroying insects.

My invention has for its object primarily to provide a form of device designed to be utilized especially for encouraging the destruction of flies, or other insects by children, or adults in a manner to adord amusement by testing the skill of marksmanship of the operator of the device, and wherein is held to one end of a channel bar an elastic band which is stretched against its tension to the other end of the bar where it is retained so as to be released for striking the insect which will be killed by the force of the blow thereof.

Another object of the invention is to provide a substantiallyL-shaped lever which is fulcrumed to the channel bar so that one of its arms is movably disposed in the groove thereof and this arm has an end portion which extends some distance beyond the retaining end of the bar for releasing the elastic band when positioned on said retaining end.

A further object of the invention is to provide a fly killing device wherein a number of itsparts may be stamped from sheet metal so as to be susceptible of being made to sell at a very moderate price, and which may be formed in various sizes and shapes.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification. in which similar characters of reference indicate corresponding parts in all the views, the said invention being more fully described hereinatter and then pointed out in the appended claims.

1n the drawing, Figure 1 is a perspective view of one form of the fly killing device embodying my invention. Fig. 2 is a side view of the operating lever. Fig. 3 is a section taken on the line Hl l of Fig. 1, and Fig. t is a section taken on the line TIL-111 of Fig. 1.

The fly killing device has a channel bar which is substantially U-shaped, as viewed in cross-section, whereby two spaced parallel flanges 11 and 12 are formed to extend upwardly to provide a longitudinal groove 13 therebetween for accommodating the long arm of a lever, as will be hereinafter more fully explained. Extending from the underside of one end portion of the channel bar 10 1s a groove bracket 14- having a body, at 15, which is approximately the shape of an irregular U to provide two spaced arms 15 and 16 so that the bracket may be conveniently carried in the hand of a person for operating the device. The free end part of the arm 15 of the Ll-shaped body 13 of the bracket 14 is curved, at 17, in substantially an L-shape and is disposed laterally from this arm. The free end part of the arm 16 of the U-shaped body of the bracket is curved, at 18, in a manner so as to be disposed from the'arm in an opposite lateral direction, and the curved parts 17 and 18 of the arms of the bracket are on the same relative plane.

Extending from the underside of the opposite end of the channel bar 10 is a retaining clip, or finger 19 which is integrally formed with the channel bar, and said finger, or clip is convoluted in a manner so that its free end portion is coiled inwardly and spaced from the other part of the finger, or

to serve as a rest for allowin the device to be.easily and noiselessly directed along the surface of a wall, or the top of a table, or the like to within striking distance of the fly, or insect to be destroyed as well as permitting the object to be accurately aimed at.

To operate the device it is charged by stretching the elastic band 21 against its tension to the other end of the channel bar 10 when it is removably disposed upon the retaining end, at 22, of the channel bar, and which is formed by making the flanges 11 and 12 thereof of a suitable depth.

Serving as means to release the elastic band 21 from the retaining end 22 of the channel bar so that it will rebound to strike the insect for killing it by the force of the blow, 1 provide a lever, as 23, which is preferably substantially Lshaped to provide two angnlarly disposed arms 24 and 25. The arm 24 of the L-shaped lever 23 is passed through an opening provided in the underside of the channel bar 10 so that the free end of this arm is disposed between the arms of the bracket -14 and the arm 25 will 5 rest in the groove 13. The lever 23 is fulcrumed, at 26, to the channel bar by providing center-punch indents 27 and 27 in the sides of the lever at the juncture of its arms 24 and 25, and striking, as shown in Fig. 3, center-punch indents 28 and 28 in the flanges 11 and 12 inwardly of the groove 13 so that the indents will be inserted in the indents 27 and 27. The arm 25 of the lever 23 is of sufiicient length to provide an integral extension 29 which pro ects some distance beyond the retaining end 22 of the channel bar. As shown, the arm 25 of the lever is considerably longer than the arm 24, and is movably disposed in the groove 13 of the channel bar so as to be properly positioned for permitting the device to be quickly operated. When the elastic band 21 is disposed on the retaining end 22, and the arm 24 of the lever 23 is pulled in a direction toward the retaining end the arm 25 of said lever will be swung in an upward direction from the groove 13 for the extension 29 to release the elastic band 21 from the retaining end of the channel bar. The energy stored in the elastic band by being stretched longitudinally of the channel bar against its tension will when released cause it to contract and strike an object with great force within a distance of its normal length.

In order to permit the device to be made so as to be sold at a moderate price, I prefer to construct its principal parts of thin sheet met-a1, and preferably make the channel bar 10 and the bracket 14 in U-shaped forms, as viewed in cross-section, so as to give these elements the required strength and rigidity. By the use of suitable dies the channel bar 10 and the bracket 14 may be struck-out and formed into shape from a single strip of metal. By bending the strip at a point thereof which provides the retaining end 22 of the channel bar, and directing the bracket portion in the proper direction the underside of said bar will be disposed in the grooves of the curved ends 17 and 18 of the arms 15 and 16 of the bracket. The end of the curved part of the arm 15 will thereby be integrally formed with the retaining end 22 of the channel bar, and the free end of the curved part 18 of the arm 16 may be Is)oldered, or otherwise secured to the channel In the foregoing description, I have embodied the preferred form of my invention, 60 but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle, or sacrificing any of the advantages of this invention, 65 therefore I reserve to myself the right to make such changes as fairly fall within the scope thereof Having thus. described my invention, I claim as new and desire to secure by Letters Patent 1.
